为了满足激光系统实战条件下的快速检测分析和保障维修的需要,采用宽光谱响应的面阵CCD成像器件和图像采集卡作为图像采集硬件,利用Visual C++6.0和Matlab混合编程设计图像采集分析软件,利用该系统开展了脉冲激光图像现场采集的相关实验,并对采集图像进行了快速分析和可视化显示。多次实验结果表明,该方法可实现对纳秒激光光斑图像的实时有效采集,结合分析软件可实现对采集图像的快速处理和空间分布特性的三维立体显示,另外该软件还能通过分析图像提供信息对比度高、易于观察的伪彩色图像。该方法的研究为激光系统的检测维修和战场激光主动侦察的目标探测与识别提供了基础的技术手段。
In order to meet the needs of rapid detection and analysis and maintenance of laser system under the actual conditions, the wide-spectral response area array CCD imaging device and image acquisition card are used as the image acquisition hardware. Visual C ++ 6.0 and Matlab are used to design the image acquisition and analysis Software, using the system to carry out on-site acquisition of pulsed laser image related experiments, and the acquisition of images were analyzed and visualized quickly. The experimental results show that this method can realize the real-time effective acquisition of nanosecond laser spot image. The combined analysis software can realize the three-dimensional display of the collected images quickly and the spatial distribution characteristics. In addition, Information contrast is high, easy to observe the false color image. The research of this method provides the basic technical means for the detection and repair of the laser system and the target detection and recognition of active laser reconnaissance in battlefield.
